Die RadeonHD-Treibersoftware ist ein Grafiktreiber für RadeonHD-Grafikkarten für AmigaOS 4.1 (amiga-news.de berichtete). Die Version 5 unterstützt nur noch "Southern Islands"-Karten (HD7000-Serie), bietet aber hardwarebeschleunigte Videodekodierung (Enhancer Software 2.2 erforderlich). Für den Sam460 wurde nun die neue Version 5.20 veröffentlicht. Die Änderungen:

• Fixed a potential crash in the find card code when the card is already in use
• Fixed an infinite loop in code to get PCIe speed capabilities, which would trigger if the parent PCIe device isn't the root controller
• Disabled GART for the Sam460 again (was accidentally enabled)
• The usleep() threshold for using the timer device was broken a while ago. FIXED
• Rewrote usleep() so it no longer needs to open/close the timer device every time there's a longer delay (lowers overhead)
• Now skips attempting to initialize the card altogether if the card is already in use
• Fixed a potential crash if initializing the driver failed
• Enabled the UVD interrupt (trap handler)
• Fixed interrupt handling for the Sam460. Caching on PCIe reads from VRAM was causing the interrupt handler to read stale data, resulting in missed interrupts which, in turn, causes a complete freeze. Added fallback and workaround code
